CNGE2FE16MS

MANAGED ETHERNET SWITCH WITH (16) 10/100TX +
(2) CONFIGURABLE 10/100/1000TX / 100/1000FX PORTS

v2.01 Jan 2012

The ComNet™ CNGE2FE16MS Managed Ethernet Switch provides robust transmission
of (16) 10/100 BASE-TX and (2) 10/100/1000TX or 100/1000FX combo ports, of gigabit
Ethernet data. Unlike most Ethernet switches, these environmentally hardened units
are designed for direct deployment in difficult out-of-plant or roadside operating
environments, and are available for use with either conventional CAT-5e copper or
optical transmission media. Diverse media selection allows for easy implementation
of point-to-point, linear add-drop, drop-and-repeat, star, or true self-healing ring and
mesh network system architectures. The 16 electrical ports support the 10/100 Mbps
Ethernet IEEE 802.3 protocol, and auto-negotiating and auto-MDI/ MDIX features are
provided for simplicity and ease of installation. 2 ports are 10/100/1000 configurable
for copper or fiber media for use with multimode or single mode optical fiber, selected
by optional SFP modules. These network managed layer 2 switches are optically
(100/1000 BASE-FX) and electrically compatible with any IEEE 802.3 compliant
Ethernet devices. Plug-and-play design ensures ease of installation, and no electrical
or optical adjustments are ever required. The CNGE2FE16MS incorporates LED
indicators for monitoring the operating status of the managed switch and network.
These units are DIN-rail or wall mountable.

INSTALLATION AND OPERATION MANUAL CNGE2FE16MS

Overview

Introduction

To create the reliability in your network, the CNGE2FE16MS comes equipped with a proprietary
redundant network protocol, X-Ring II, which provides users with an easy way to establish a
redundant Ethernet network with ultra high-speed recovery time of less than 10ms. Also, the
extended MTBF (Mean Time Between Failures) ensures that the CNGE2FE16MSwill continue to
operate until a Gigabit network infrastructure has been established without requiring any extra
upgrade costs.

The CNGE2FE16MS also comes equipped with 2 Gbps (gigabit) Ethernet combo ports; each
combo port consists of a copper and a SFP sockets. The combo ports can be used for the
application of wideband uploading and especially long distance transmission by connecting the
SFP socket to fit the field request flexibility.

Heavy Duty

Designed with metal housing, the CNGE2FE16MS provides the rugged construction that complies
with IP30 standards.

Dual Power Inputs

The redundant power input design for the CNGE2FE16MS provides a backup power solution.
With both the power inputs supplied, if a failure occurs the other supply will be activated to keep
the system continually operating. When one of the power inputs fails, the P-Fail LED indicator
illuminates and sends an alarm through the relay output as notification.

Flexible Mounting

The CNGE2FE16MS can be mounted on the wall or on a standard DIN rail, so it is suitable for any
space-constrained environment.

Wide Operating Temperature

The operating temperature range of the CNGE2FE16MS is between -40 and +75ºC. With such a
wide range, you can deploy the CNGE2FE16MS in some of the harshest industrial environments.

Easy Troubleshooting

LED indicators make solving any challenges easy. Users can identify the status of the switch by
observing the LED indicators with the definition table.

N-Key Quick Installation

An optional accessory is offered for the CNGE2FE16MS for quick installation especially when you
are planning to do routine tasks. Users can simply plug the accessory known as N-Key into the
console port for system configuration backup/restoration.

RJ-45 Cabling

Use four twisted-pair, Category 5e or above cabling for the RJ-45 port connection.

The cable between the switch and the link partner (switch, hub, workstation, etc.) must be less
than 100 meters (328 feet) long.

The RJ-45 copper ports will auto-sense for 10Base-T, 100Base-TX, or 1000Base-T connections.
Auto MDI/MDIX means that the switch can connect to another switch or workstation without
changing straight through or crossover cabling.

2 Receive Data minus (RD-) Transmit Data minus (TD-)

Gigabit Copper/SFP Combo Port

The CNGE2FE16MS is equipped with Gigabit Copper/SFP combo ports. The Gigabit Copper
(10/100/1000T) ports should use Category 5e or above UTP/STP cable for the connection speed
up to 1000Mbps. SFP slots supporting dual mode to toggle the connection speed between 100
and 1000Mbps are used for connecting to the network segment with single or multi-mode fiber
optics. You can choose the appropriate SFP transceiver to plug into the SFP socket with proper
multi-mode or single-mode fiber cable according to that transceiver.

Note The particular SFP/Copper Combo port is deemed to be a single port that either the SFP or

Copper port operates; the SFP and Copper ports cannot both operate at the same time.

The SFP port has the higher priority than the corresponding copper port; if you insert the

1000M SFP transceiver (which has connected a fiber cable between that transceiver and the

remote node) into the SFP port, the connection of the corresponding copper port will link
down.

If you insert the 100M SFP transceiver into the SFP port even without a fiber cable between

that transceiver and the remote node, the connection of the corresponding copper port will
link down immediately.

Wiring the Power Inputs

Please follow these steps to connect power lines from the terminal block to the compliant external
DC power source.

» Before wiring, make sure the power source is disconnected.

» Using a wire-stripping tool, remove a short piece of insulation from the output wires of the DC

power source.

» Identify the positive and negative polarity feed positions for the terminal block connection.

See the symbols printed on the panel indicating the polarities and DC input power range in
voltage.

Figure 12 – Plugs for Power 1 & Power 2

» Insert the exposed wires into the terminal block plugs. Only wires with insulation should extend

from the terminal block plugs. Note that the polarities between the wires and the terminal
block plugs must be positive-to-positive and negative-to-negative.

» Use a slotted screwdriver to tighten the captive screws.

Figure 13 Captive Screws for Fixing Wires

Attention: Use Copper Conductors Only, 60/75°C, tightening to 5 lb-in

The wire gauge for the terminal block should be in the range between 12~ 24 AWG.
